RX 480. I noticed a while ago that overclocking didn't work on drm-next-4.17-wip/drm-next-4.18-wip, but now it's gotten into mainline. With linux 4.16.3 overclockling works fine. With 4.17-rc1 the setting doesn't "stick" and the clocks aren't increased: root@c-pc ~ # cat /sys/class/drm/card0/device/pp_sclk_od 0 root@c-pc ~ # cat /sys/class/drm/card0/device/pp_dpm_sclk 0: 300Mhz * 1: 608Mhz 2: 910Mhz 3: 1077Mhz 4: 1145Mhz 5: 1191Mhz 6: 1236Mhz 7: 1288Mhz root@c-pc ~ # echo 2 > /sys/class/drm/card0/device/pp_sclk_od root@c-pc ~ # cat /sys/class/drm/card0/device/pp_sclk_od 0 root@c-pc ~ # cat /sys/class/drm/card0/device/pp_dpm_sclk 0: 300Mhz * 1: 608Mhz 2: 910Mhz 3: 1077Mhz 4: 1145Mhz 5: 1191Mhz 6: 1236Mhz 7: 1288Mhz
